ROLLING TOOL AND HOLDING DEVICE.

Application filed March 8, 1923. Serial No. 623,079.

To all 'whom it may concern.'

Be it known that I, CHARLES R. Bownns, a citizen of the United States,and a resident of Frankfort, county of Clinton, and State of Indiana,have invented a certain new and useful Rolling Tool and Holding Device;

Y and I do hereby declare that the followinfr is a full, clear, andeixact description thereo reference being had to the accompanylngdrawings, in which like numerals refer to like parts.

This invention relates to a repair tool for attaching a connecting keyto a shaft by the usual beading or rolling operation.

The main object of the invention is to provide a small hand-operateddevlce for rolling the periphery of the metal connecting key and forcingit into an annular groove in the shaft to which 1t 1s to be secured, thedevice being small and simple in construction so as to be available tothe small garage and machine shop.' D

One feature of the invention resides 1n the method of supporting theattaching key and shaft in position to be operated upon; and anotherfeature thereof resides in the meansfor adjustably clamping and securingthe same in a suitable vise or holder so as to permit the key to berolled at a given distance from its end.

Still another feature of the invention'resides in the beading tool andits construction, whereby the engaging rollers thereof will roll thebead upon the rotation of the tool, the pressure applied thereby beingneutralized by the relative positions of the rollers.

The full nature of the invention will be understood from theaccompanying drawings and the following description and claims.

In the drawings, Figure 1 is a plan view looking down on the tool andholder therefor, with the shaft removed. F ig. 2 is a side elevationshowing the tool applied to* the shaft in operative position. F ig. 3 isa central vertical section through the shaft, and a portion of theholder and tool.

In the drawings there is shown a holding socket 10 which is annular andcup-shaped mounted upon the base 11. On the opposite end of the base 11,there is another holder A12 of suitable diameter for supporting andsecuring the movable pinion mounted on the shaft, which, however, doesnot form a part of this invention. Secured within the socket or holder11, and loosely mounted therein, there is a receiving member 13 providedwith a central bore or recess for receiving the bifurcated or key end ofthe connecting key 14. Rigidly secured in the body ofthe member 13,there is an upwardly extending pin 15 positioned to extend between'thebifurcated ends of the key 14 for preventing its turning therein. Forlocking the member 13 rigidly in the socket 10, there is a set screw 16.

The shaft 17 which is hollow and provided with external screw threadsupon which the pinion 18 isv mounted, is provided with a head orenlarged portion 19 which is formed integral therewith. Said head 19 isprovided with a reduced portion 20 in which is formed an annular groove21 to receive the bead 22 which may be rolled therein by the toolhereinafter to be described. Rigidly secured at the opposite end ol theshaft from the head 19, there is a collar 23, all of which constructionforms appart of a starter shaft for starting an internal combustionengine through the medium of an electric motor in the usual manner. Foradj ustably clamping the shaft in position, there is provided a rod 24having a head 25 keyed to one end thereof', said head being providedwith the wings 26 for enabling it to be readily grasped and turned. Saidshaft is adapted to extend through the hollow shaft 17 in the collar 19and is provided with screw threads on the opposite end adapted to screwthrough an internally threaded central opening in the member 13, wherebythe end thereof will engage the bottomof the socket 10. Mounted adjacentthe head 25, there is a wing nut 38 arranged to screw about the upperthreaded portion of the rod and contact with the top of the collar 23.For mounting the shaft and connecting key in position to be operatedupon and properly adjusting the. same, the key 14 may be first mountedin position within the member 13 so that it is engaged by the pin 15 andthe shaft may then be mounted thereon so that the reduced portion 2O ofthe collar 19 extends into the surrounding shell of the connecting key14. The rod 24 is then inserted through the shaft andA screwed throughthe member 13 until it engages the bottom of the socket 10, so thatfurther turning thereof will cause the socket 13 to rise until it liftsthe key 14 and shaft to lll) the desired elevation. 'llhe set screw 16may then be screwed tightly against the member 13 for securely lockingthe same, and the wing nut 38 may be screwed down on the rod 24 so as torigidly clamp said shaft and key 14to the member 13. It will beobserved, therefore, that after the proper adjustment is made, the partsto b e operated upon are rmly held in fixed position within the socket10.

Before the parts are assembled and secured in place, as above described,the tool should be placed in position resting on the top of the socket10, as shown in Figs. 2 and 3. Said tool comprises a body portion 27having an annular opening 28 of substantially the same diameter as theinterior of the socket 10, and is milled out for providing a laterallyextending opening 29 in which the rollers 30 may e rotatably mounted.Extending from one end of the body portion 27, there is a handle 31; andfrom the other end thereof, there is Ia longitudinally extending recessin which thel block 32 is slidably mounted, said block having abiturcated end in which the roller 33 is rotatably mounted. rlheadjusting screw bolt 34 is adapted to be screwed in the end o the tool,so that its inner end abuts the end of the block 32' for forcing itinwardly. y

The screw bolt 34 is provided with a longitudinally extending handle 35having in the end thereof a cross rod 36 for turning the same andforcing the roller 33 inwardly under pressure.

In operating the tool, assuming that it has been placed upon the socket1() and the connecting key 14 and shaft 17 secured in position throu hthe opening 28 therein, as above descri ed, the handle 35 is turned bythe rod 36 until the rollers 30 and 33 are forced about the periphery ofthe key 14 at three points under pressure. The position of the key 14will have been previousl adjusted by operating the rod 24 vertlcallyuntil the annular Groove 21 about the reduced portion 20 of the collar19 is directly opposite the beadin flan e 37 of said rollers. After thero 1ers ave been forced under pressure against the key 14, the handles31 and 35 of the tool may be grasped and the tool turned slowly aboutthe key so that the beading langes 37 will force the metal of the key 14into the groove 21 about the entire circumference thereof.

The beading operation will thus be performed without removing the pinion18, collar 23 or associated parts from the shaft 17, and the pressureapplied by the rollers will be entirely sustained by the shaft or collarso that said shaft will not be, even in the slightest degree, bent outof alignment.

The invention claimed is:

l. In a device for attaching a member to a hollow shaft, thecombinationof a holding means for securin said shaft and attachmenttogether, inc uding a rod adapted to extend t rough said shaft andattachment, .clampin members adapted to screw on the ends o said rod forclamping said shaft and attachment together, a mounting 4into which saidrod and the clamping member on one end thereof are adapted to extend,means for locking said rod in said mounting, andv a tool supported onsaid mounting and adapted to surround said rod so as to engage aboutsaid shaft and attachtiti ment therefor for rolling an attachment ,l

bead thereabout when rotated with respect to said mounting. p f' 2. In adevice for attaching a member to a hollow shaft, thel combination of ameans for holding said shaft and attachment in position withrespect toeach other includin a rod adapted to extend'through said ho low shaftand attachment, a clamping nut adapted to screw on one end of said rod,a recessed member through which the other end of said rod is adapted toscrew, a mounting for receivingv said member against which the end ofsaid rod may abut, a pin in said member extending into said attachmentfor preventing the rotation thereof, means t r locking said member andmounting rigid y together in adjustable position, and a tool rotatablysupported on said mounting in position to surround said attachment andshaft for rolling an attaching bead thereabout at a given position lixedby the adjustment ont said member.

ln witness whereof, ll have hereunto alixed my signature.
